Three roman coins [επιλυμένο]

Hello everyone! I have these three roman bronze coins that i need help with, i’ve tried finding them in the catalouge but i haven’t had any luck. Any help appreciated! 

1  

The first coin has a diameter of around 25 mm and weighs 12,81 grams. You can only see some of the lettering of which i can read ”caian” on the obverse and ”nona” on the reverse. 

2

The second coin is quite irregular so the diameter is around 24,5 mm to 27,2 mm and it weighs 13,49 grams. none of the lettering on the obverse is visible but on the reverse i could make out ”vilcei” or ”vice” in the little circle and ”sc”. 

3

The third coin is also very irregular and has a diameter of around 21,6 mm to 24 mm and weighs 12,13 grams. I can’t make out any lettering on this coin but i might see something on the obverse. 

I found a coin that’s pretty similar to the third coin, the portrait and some other small details are slightly different, but the design and weight matches my coin.

Coin 3 is a Roman Provincial Tetradrachm from the city of Alexandria in Egypt. Struck under Septimius Severus. You can see the date (Year 2) on the top of the reverse (L B). This means that it was struck either in 193 or 194 AD. The RPC entry is linked below

Thank you so much! Interesting to know all of them are above 1800 years old, i thought they were much less old! Also very nice to learn that one of them is part silver.
